Description

The gas-liquid separation self-sucking device
Technical field:
The utility model is the match equipment that belongs to pump.
Background technique:
At present, submerged pump, Under Water Pumps, self-priming pump, vertical diagonal flow pump are used widely, reach good transfusion effect, but also have the following disadvantages:
1. submerged pump: because of structural limitations, flow, lift parameter area are too narrow; Submerged pump limits because of operating conditions, and the blade quantity of pump is few, so inefficiency; The submerged pump working portion must be in the medium that is transferred, not only installation, maintenance inconvenience, and in the medium of complex chemical composition, soak for a long time, cable and Sealing are fragile, cause the generation of accident;
2. Under Water Pumps and vertical diagonal flow pump: axial length is apart from transmission, and guide bearing mechanical friction causes that mechanical loss increases, the unit inefficiency; For for the guide bearing lubricant medium, on the support column jecket overflow hole is arranged, return the decrease in efficiency that liquid makes pump; Guide bearing very easily weares and teares, and causes main shaft fragile, needs often to take out maintenance in darker pond formula reactor, brings very big difficulty to the user.
3. self-priming pump: in the gas-liquid separation process, have partially liq to reflux all the time, cause the partial volume loss, the efficient of pump is reduced; The gas-liquid separation self-sucking device is one of internal structure of self-priming pump, makes it the self-priming pump complex structure, and application area is narrow; Conveying contains the liquid (as sewage) of impurity, and return port very easily stops up, the forfeiture suction capacity.
The model utility content:
The utility model is exactly at the problems referred to above, provides a kind of pump that makes can work on the ground fully, and high working efficiency, installation and maintenance are the gas-liquid separation self-sucking device easily.
The utility model adopts following technological scheme: the utility model comprises having liquid entering hole, the liquid container of liquid outlet, have the gas-liquid separator of liquid entering hole, liquid outlet, its structure outline is to link to each other with the reflow pipe with stop valve between the liquid outlet of liquid entering hole, gas-liquid separator of liquid container, and the side of the injection pipe of the liquid entering hole below of liquid container is a sucking pipe; The bottom of liquid container has sewage draining exit, and the top of liquid container is spout, has the outlet pipe of stop valve, is provided with sucking pipe between the outlet pipe of liquid container and the liquid outlet.
The beneficial effects of the utility model:
1. pump is worked fully on the ground:
When using the utility model, with liquid container, gas-liquid separator gets final product work after linking to each other with supporting pump respectively, and the interior installation, maintenance work of medium of original submerged pump, Under Water Pumps, vertical diagonal flow pump can be carried out fully on the ground, provides very big convenience to the user; Also can be with the supporting use of multiple pump (for example, submerged pump, Under Water Pumps, vertical oblique pump, centrifugal pump etc.);
2. high working efficiency:
The utility model can overcome submerged pump in the past with the supporting use of pump, Under Water Pumps, vertical diagonal flow pump inefficiency, the shortcoming that application area is narrow; High by 8~15% than the efficient of Under Water Pumps, submerged pump, self-priming pump.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model structural representation when being used to carry sewage;
The actual user mode schematic representation of Fig. 3 the utility model.
Embodiment:
The utility model comprises having liquid entering hole 19, the liquid container 4 of liquid outlet 1, have the gas-liquid separator 6 of liquid entering hole 5, liquid outlet 7, link to each other with the reflow pipe 12 with stop valve 11 between the liquid entering hole 13 of liquid container 4, the liquid outlet 10 of gas-liquid separator 6, the side of the injection pipe 3 of liquid entering hole 13 belows of liquid container 4 is a sucking pipe 17; The bottom of liquid container 4 has sewage draining exit 2, and the top of liquid container 4 is spout 18, has the outlet pipe 16 of stop valve 15, is provided with sucking pipe 14 between the outlet pipe 16 of liquid container 4 and the liquid outlet 1.
For strengthening the venturi effect of liquid at gas-liquid separator 6, gas-liquid is better separated, can in gas-liquid separator 6, be provided with reverse baffle plate 21 with through hole 22.
Be convenient to sewage and flow out from gas-liquid separator 6, and reach better gas-liquid separation effect, gas-liquid separator 6 tops are oblique orientation wall 9, and the upper end of oblique orientation wall 9 is a liquid outlet 7; The liquid entering hole 5 of gas-liquid separator 6 belows should be corresponding with oblique orientation wall 9.
Also can in the injection pipe 3 of the liquid entering hole 13 of liquid container 4, be provided with liquid-spraying pipe 23, increase the effect of bleeding of sucking pipe 17 with this.
Below in conjunction with a description of drawings course of action of the present utility model:
During use, at first import, the outlet with supporting pump 25 links to each other with the liquid outlet 1 of liquid container 4, the liquid entering hole 5 of gas-liquid separator 6 respectively; The liquid entering hole 19 of liquid container 4 links to each other with the suction pipe in the medium 20, and the liquid outlet 7 of gas-liquid separator 6 links to each other with output tube 8.Fill with the medium that is transferred by spout 18 to liquid container 4, in the fluid injection process, the stop valve 15 of outlet pipe 16 is opened, after waiting to fill with liquid, the stop valve 15 of outlet pipe 16 is closed.Starting electrical machinery 24, pump 25 operations; Liquid from liquid container 4 in pump 25 is delivered to gas-liquid separator 6, part gas is discharged by output tube 8 with liquid, part gas returns again in the liquid container 4 with a part of gas-liquid, and the sucking pipe 14 in the liquid container 4 is discharged the import that this part gas imports pump 25.The liquid flow velocity in injection pipe 3 that returns at a high speed in the reflow pipe 12 is very high, makes sucking pipe 17 produce negative pressure, bleed; The liquid that is transferred under the barometric pressure effect, constantly from low level flow to liquid container 4, through pump 25, gas-liquid separator 6 to output tube 8, when treating that pump 25 enters normal working, the stop valve 11 on the closing volume pipe 12 gets final product.
